hi mga Mii pwede Po Ako Pa help about my trans V.

When the placenta completely covers the internal cervical opening (os), it's called complete placenta previa, a condition where the placenta attaches low in the uterus, blocking the baby's exit, and is diagnosed by ultrasound, typically requiring a cesarean section (C-section) to prevent severe maternal bleeding and complications. It's a major cause of antenatal bleeding, but some cases diagnosed early may resolve as the uterus grows.
